Static code analyzers and the programming-by-contract methodology help developers significantly reduce the number of coding errors in their code. However, this is not sufficient in safety-critical software development. It is important to formally prove that the design of a software component is correct.
There are a number of fairly complex methods to do this, along with tools to automate this process. In this recipe, we will explore one of the tools for formal software validation, called CPAchecker (https://cpachecker.sosy-lab.org/index.php).
